If you still support older iOS versions, you can’t use this new API. Also, if you have embedded Storyboard references, you cannot use Initializer Injection for the child ViewControllers (only for the top-level parent!).

But if you move all instantiation to a centralized place, that should not be a big problem as you can cleanly instantiate and compose the ViewController with all its dependencies (e.g., using Property or Method Injection).
